ARNOLD HEUCKENDORFF, OF OAKLAND, CALIFORNIA.

PEA-HULLING MACHINE.

Application filed May 24, 1920. Serial No. 333,745.

To all whom it may concern:

a specification.

This invention relates to improvements in pea shelling machines, the principal object being to provide a device for the purpose which will effectually shell all the pods and will not crush the peas removed from the pods and will leave the pods clean, contrary to the condition of the pods and peas-when put through the machines at present on the market for this purpose.

This is accomplished by means of a series of graduated drums, around which all the pods must pass, but having cooperating means so arranged that the peas are removed from the plane of the drums assoon as they are shelled, and so are not. acted on by an remaining drums once they are shelled, thus preventing the shelled peas from being crushed.

The particular construction employed is set forth more fully hereinafter, the description being taken in connection with the accompanying drawings, to which reference is made, and in which:

Figure 1 is a side view of the sheller.

Figure 2 is a view of the opposite side from that shown in Fig. 1.

FigureB is a. vertical sectional view of the pea sheller.

Figure i is a top plan view of my invention.

Figure 5 is a sectional view taken on the line 55 of Figure 3.

Figure 6 is a sectional View taken on the line 6-6 of Figure 3.

Figure 7 is a sectional view taken on the line 77 of Figure 3.

Figure 8 is a front View of the sheller with the cover raised.

Referring more particularly tothe drawings, the numeral 1 indicates an appropriate casing having side walls 2, a rear door 3 and a front door 4. Journaled in the side walls 2. are three graduated drums 5, each. succeeding drum being below and in front of the preceding drum. On each drum are radiating fingers 6, said fingers being placed closer together transversely on each succeeding drum. Stationary finqers 7 project from walls 8 to the rear of the drums 5. The stationary lingers 7 are positioned between the rotating lingers 6 so that the pod is held between them and cut or broken open which allows the peas to drop out. Below the first two drums are placed screens 9 which allow the peas to drop through while the pods are retained and pushed forward into the next drum. Scraper plates 10 are set in front of each drum to take any pieces of pod that may adhere to the fingers (5, and prevent the same being carried around again. A sieve 11 below the drums 5 is hinged at 12 to a plate 13, the forward end resting on a block 14. Under the sieve l1 and movable therewith is a plate 11, the peas passing through the sieve onto the plate and being then delivered to a spout 15 opening into a mouth 16 to, receive the peas from the plate. A feeding draper 17 travels over rollers 18 and 19 and a gate QOinidway of the draper regulates the number of peas fed to the machine, the draper 17 taking the peas as they are fed down a chute 21.

On a shaft 22, on which the topmost drum 5 is mounted, is secured an operating crank 23, on the other end of'which shaft is a gear 24. Meshing with the gear 2a; is a gear on a shaft 26, on the other end of which is a gear 27 meshing with a E28 onthe draper roller 18. A gear 29 meshes with the gear 24L, to drive a shaft 30, on the other end of which shaft is a gear 31, meshing" with a gear 32 connected to the second drum 5. To a shaft 33 towhich the gear 31, is secured, is secured a second gear 34 meshing with a gear 35 to drive the third drum 5. Un the opposite end of the third drum 5 is a spur gear 37 meshing with a pinion 88 to which an arm 39 is secured. The arm 39 is secured to the sieve 11' and causes it to oscillate by reason of the rotation of the gear 88. ll tightening screw 40 is secured to a U-shaped yoke ll secured to the bearings of the roller 19, by means of which the draper 17 may be tightened.

The operation of my invention is as follows:

Green peas in the pod are fed, into the chute 21 and are carried forward by the draper 17, the gate 20 regulating the nun1- ber of peas passing into the drums so that they enter one at a time. The pods pass through the first drum, are engaged by the empty pods fingers (3 and 7 as previously described, and the peas that are shelled drop through the screen 9 onto the screen 11. The pods that have not been opened are then )ushed torment, the topn'iost ot said drums beingl? ar-.

god to receive the pods thereon and pass them in the succeedingdrums, lingers on the drums, stationary lingers cooieratingr with the drum-lingers to break open the pods passing in the plane oi? the lingers with the rotation ol he drums, a stationary screen under each drum adapted to receive the peas therethrough but to retain the pods, the drums being; so positioned that each screen will clear the drum below, a slanting sieve under all the screens adapted to receive all. the peas thereon and the from the lowermost drum, a plate below the sieve, the peas dropping throu h the latter but the pods being retained thereon, a discharge from the sieve for the pods, and a discharge outlet from the plate for the peas.

2. A pea sheller comprising a plurality or rotating drums arranged in spaced ali nmcnt, the topmost of said drums being arranged to first receive the pods thereon and to pass hem to the succeeding: drums, lingers on the drui'i'is, stationary fingers cooperating with the drun'i-lingers to break open the pods passing in the plane of the lin ers with the rotation of the drums, a

St on under each drum adapted to receive the p( theretln'ough but to retain the pods,

the drums being; so positioned that each en will clear the drum below, a slantsieve under all the screens adapted to r f-ive all the peas thereon and the empty pods from the lowermost drum, and means tor oscillating: the last mentioned sieve with the rotation of the drums, the peas being ing with the drum-fingers to break open the podspassing in the 1313118 ofthe fingers with the rotation of the drums, stat-ioi'izwy means whereby the peas so shelled will be immediately withdrawn "from the plane of the drums, and means whereby all the pods will be passed onto the succeeding drums.

, t A pea sheller comprising a plurality of rotating drums arranged to receive the pens successively, fingers on each drum, stationary lingers between which pass the fingers on sand drums, the fingers on each succeedingdrum being spaced closer longitudinally of the drum than the fingers of he preceding drum, a stationarysieve beow said, drums through which the sielled wens fall from said drums, plate under said sieve upon which, the peas from the sieve fall, and means for oscillating said sieve.

5. A pea sheller comprising a plurality of rotating drums arranged to receive the peas successively, lingers on each drum, stationary fingers between which pass the fingers on said drums, the fingers on each succeeding drum being spaced closer longhtudinally of the drum than the fingers lot the preceling drum, and a stationary perforated plate under each drum through which the shelled peas from the drums drop.

0. In a pee sheller, a plurality of rotating drums having their axes in a sloping; plane, fingers on the drum,-stationary fingers between which the drum fingers pass, a stationary screen under each of the drums through which the peas are forced by the drum lingers and a shaking sieve extending under all of the fingers and adapted to receive both the peas and the hulls.

In testimony whereof I my signatore.
